Limits and Scanners

Watlow single- and multi-loop limits provide cost-effective solutions for single- and multi-channel, temperature monitoring. Limits monitor the process value where thermal system protection is needed, closing a contact output for normal operation and opening that contact to shut down the process or equipment when the value is outside the safe range.

Various configurations offer user-selectable or fixed-configuration sensor options including thermocouple, process, RTD and thermal switch inputs as well as user-settable or fixed limit values. Models with displays have user-selectable temperature units. Other features include sensor break protection, industry standard I/O options and UL® and CSA approval. All limits and scanners are RoHS compliant. Limits have FM approval for performance in limit applications. Watlow limits are designed and manufactured to withstand harsh industrial environments and come with a three-year warranty.
